Hi all!
I have my Xperia M2 with the latest firmware: 18.6.A.0.182.
I want to root it, and install a custom recovery, and i know how to do all of this through this forum. But I need to unloock my bootloader.
What's the problem?
If you go here: (i can not post links, the developer sony / unlockbootloader) and warns you:
Important note! In order to unlock your Xperia™ M2 you need to be on software version 18.3.C.0.37. Also beware that booting this device the first time after unlocking the boot loader may take a long time.

I don't know why this...
Searching in google, the people recomends to use flashtool to unlock the bootloader.
What will happen if i intend to unlock it and something goes wrong? I don't know how to solve a soft-brick withouth an unlocked bootloader.
Thanks for your help.
Hey, first do it the official sony way flashtools doesn't work for many including me when i unlocked my bootloader. http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
Second if anything goes wrong, just reflash your firmware (jellybean, kitkat, lollipop whatever) through flashtools and it will be back to stock.
Unlocking your bootloader there is not much which can go wrong.
Btw, you will lose your DRM keys. 2 of them i think for buying stuff through ps store.
Also if you run into problems post here we'll help.
Now I have root with KingRoot. If I make a backup of TA partition i can restore DRM keys when I like it, no?
And the magic question for me is: How I flash original firmwares if the bootloader is locked? I only need locate the right FTF and with flashtool is enought?
Thank you!

Yes you can restore your DRM keys backup if you want in the future.
And if you want to flash a FTF on locked bootloader you can use Flashtool by Androxyde or Xperia Companion.
Ok, thank you all, I'll try to backup DRM keys and unlook the bootloader and I'll post the results!

Hello again D:<
Another question (u_u. I've never had a Xperia smartphone before, so :c).
I don't know about how install the Generic Xperia M2 4.4.2 Firmware, well, I know something, like use Flashtool for mount the FTF file into the phone. But, about the TA Backup?.
I'm kinda unpredictable, so, summarizing everything... Could you please give a tutorial about those steps that I must follow to install the 4.4.2 Generic Firmware for Xperia D2306?
Thanks for everything.
Regards!

Thanks, so, I suppose will work fine the TA Backup from that link. I'll check it.
But, my Info Service from Bootloader allow or not says this: "Bootloader unlock allowed: No", so basing on that assumption, I don't think that Bootloader can be unlocked. So, I have the question about is it extremely necessary has the bootloader unlocked for flash the 4.4.2 Generic KitKat D2306 Model with Flashtool :c.
Thanks
You can flash ftf with locked bootloader.
Sent from my D2303
But be careful, they only did kernel to D2303/D2305.

But, the kernel is only used for people who use ClockWorkMod Recovery for install ROM or Root with Unlocked Bootloader. I don't try to install ROM (CyanogenMod, that is based on D2303 model), neither Root with Unlocked Bootloader ('Cause I can't unlock bootloader). I'm gonna use Flashtool, and other comments says nothing about Kernel and ClockWorkMod Recovery.
Thanks either way :3.

Follow the process on the linked page above If you don't already have the Android SDK and ADB installed, you'll need to do that, or eventually just install Minimal ADB and Fastboot.
Edit: apparently got ninja'd.
Edit2: ups, apparently I also suck at reading questions - so unless you're looking to unlock your bootloader, just follow robkellie11's link.
You can root without unlocking bootloader Bro, downgrade to 5.0.1 and use kingroot root
I also want to root the z3 5.1.1. Can i restore it back after root and unlocked bootloader so i can still use the warranty?

If you Backup your TA Partition, you can restore the DRM Keys and your bootloader status, there for you should be able to use your warranty IF you're on a stock rom while sending your phone for repairs etc.
You can backup your TA Partition by using THIS
Folks, I unlock the bootloader xperia d6633, now I can no longer update the device the following screen
Settings> About Phone> Software Update
I wanted to know how do I relock the bootloader, and able to upgrade to version 23.5.A.0.575
I'm a beginner, possibility ,possibility of video?
thanks
:confuso:
Edit: you can relock the bootloader without TA, there's an option in flash tool. DRM keys are still gone though
It is made clear that once you unlock the bootloader warranty is lost and many Sony software features such as those affecting camera quality are lost.
You will need to update manually with flashtool which will work fine with unlocked bootloader and is not very difficult.
http://www.flashtool.net/index.php
All this means is you need to get the firmware as an FTF file for your phone probably from here on XDA (make sure its for D6633) and then use this tool to update the phone. Google is your friend for a guide.
Edit: I probably need to tell you DO NOT try to flash a TA partition from anyone else or in flashtool (when there are tick boxes for "exclude" make sure you exclude .ta files) or you will hard brick the phone (dead as dead can be).
Ideally if you're going to unlock the bootloader you should root kitkat firmware and then take a TA partition backup to be able to restore DRM at a later time if you feel the need to.

Did you backup the TA partition? If you did then go ahead and restore it to your phone.
If that means nothing to you then you didn't and you cannot re-lock the boot loader.

Really? I missed that bit I thought there was no way without TA
Okay I learnt something new
Don't just say it though explain how so he can do it!
(And so I can learn instead of passing wrong information again like an idiot )
Edit: found a tutorial. They explain relocking just after how to unlock

Unfortunately though this does not restore DRM keys (I wish though) so as said some software on stock rom won't work, but there is a flash able zip to enable most of it though
I got a unlocked bootloader XZ dual 8332, download tft from Xperiafirm, and at the end of flash session i got a erro :
Code:
[COLOR="Red"]01/025/2016 17:25:54 - ERROR - Have read only 524256 byte(s) instead of 780004 byte(s)
01/025/2016 17:25:54 - ERROR - Error flashing. Aborted[/COLOR]
What does it's meanning ? My phone got a "update failed" when turn on now.
Do we need check some "check box" or anything before flash a tft file ?
And is anyway to relock bootloader if we want repair by Xperia Companion or update through OTA ?
Thanks.
AFAIK flashtool is not compatible with 7.0 yet and there is no way to relock your bootloader yet.

When you flash a modified kernel with drm fix your drm is working. When you relock your bootloader your phone got factory reset itself and drm still in your phone.
Try to update via ota
After that because you are unlocked try to flash flashfire and install supersu to be rooted and searsh to drm fix file and flash it manually from any root file manager.
Another step
Uodate your unlocked phone ota update
Restart you phone
It should be working now with no drm fix
Poweroff your phone
Enter falshmode (power button + volum up) you see a purpul led
Enter adb and flash supersu sr5
It should work after flash drm manually
Try and reply please

So much wrong info here.
Firstly, once you unlock the bootloader the TA partition where the DRM keys are stored is formatted. They are gone forever. Relocking the bootloader does not bring them back. The DRM fix replicates (Not 100% fixes) the missing functions and this fix only works on rooted phones, which you cannot have with a locked bootloader.
Secondly, do not try and update OTA with an unlocked bootloader. It could brick your device.
Are there any known issues when unlocking the boot loader?
A: Yes. When you select a device, any known issues for that device will be displayed. In addition, the following generic issues have been reported:
•Some users have experienced problems when they are accepting over the air upgrades. Therefore we do not recommend users to accept over the air upgrades, after having unlocked the boot loader. For additional information, check out the XDA Forums for hints and tips from the community.

Xperia companion will fail. It will detect unlocked bootloader and not work.
OTA 'may' work, but as I said and quoted it 'may' also brick your device. Do it at your own risk.

Everything you wrote is absolutely correct.
PC companion detects that the device is unlocked & OTA's automatically fails to install.
So apparently, relocking & updating is possible but relocking means you can no longer use the stock camera anymore.

Unlocking your bootloader again on Nougat using official Sony guide fixed the issue for me.
Make sure you don't use Flashtool to unlock your bootloader on Nougat.

Flash FTF via flashtools and wipe everything it's pretty straightfoward, you can get it here. Download, open xperifirm, flash.
To restore drmkeys you need to have a backup before you unlocked your bootloader otherwise your DRM keys are lost forever and you will have to flash either a kernel or
drm fix.
